Bank 2 = drivers side, upstream = front one..

Check the wiring of the front drivers side o2 sensor, make sure it's not twisted, broken, wiring harness plugged in, etc. I'm not sure why putting MIL eliminators in would affect the FRONT sensor, but if that's your code, that's what it's talking about.
